Zopiclone and Cannabis: Interactions and Health Risks

Zopiclone is a prescription-only medicine used for short-term management of insomnia, while cannabis is increasingly used both recreationally and in limited medical settings. Although both can affect sleep and relaxation, combining them can cause harmful and potentially dangerous side effects. This article explains how the two substances interact, the risks of using them together, and why you should always disclose recreational drug use to your healthcare provider.

Key Takeaways

Zopiclone is a short-term treatment for insomnia, prescribed for up to 2–4 weeks.
Cannabis can have medical applications but also carries risks, particularly with recreational use.
Combining the two enhances sedation, increasing the risk of drowsiness, confusion, and breathing difficulties.
Potential side effects include memory issues, poor coordination, accidents, and difficulty waking.
Always inform your doctor about recreational drug use before starting Zopiclone or any prescription medicine.

What is Zopiclone Used For?

Zopiclone is a non-benzodiazepine hypnotic prescribed to treat short-term sleep problems, particularly when insomnia is causing significant distress or affecting daily life. It helps people fall asleep faster, reduces nighttime waking, and improves sleep quality.

Because prolonged use can lead to tolerance and dependence, Zopiclone is generally prescribed for no longer than two to four weeks. It is unsuitable for some patients, especially those with a history of substance misuse, breathing disorders, or certain psychiatric conditions.

What Is Cannabis Prescribed For?

Cannabis contains active compounds known as cannabinoids, most notably THC and CBD. In the UK, cannabis-based products for medicinal use may only be prescribed by specialist doctors under strict circumstances, such as:

Severe epilepsy (e.g., Dravet syndrome, Lennox–Gastaut syndrome)
Chemotherapy-related nausea and vomiting
Chronic pain linked to multiple sclerosis
Muscle stiffness and spasms caused by MS

Recreational use remains illegal in the UK and carries health risks, especially when mixed with prescription medication.

How Do Zopiclone and Cannabis Interact?

Both Zopiclone and cannabis slow activity in the brain and central nervous system. When taken together, their sedative effects are amplified, leading to excessive drowsiness, dizziness, and impaired alertness.

This interaction can significantly increase the risk of accidents, particularly when driving, operating machinery, or performing tasks requiring concentration and coordination. The unpredictability of cannabis strength—especially in unregulated products—further increases the danger.

Potential Side Effects of Mixing Zopiclone and Cannabis

Combining the two can result in several serious side effects, including:

Extreme drowsiness – excessive sleepiness that may affect daily functioning.
Difficulty waking up – deeper sedation that can make waking difficult, even in emergencies.
Confusion and memory problems – impaired concentration and forgetfulness.
Impaired coordination – higher risk of falls, road accidents, or injuries.
Respiratory depression – slowed or shallow breathing, which can become life-threatening in rare cases, especially with high doses or when combined with alcohol.

Why You Must Tell Your Doctor

If you use cannabis or any other recreational drugs, it’s essential to tell your healthcare provider before starting Zopiclone. This information allows them to assess whether Zopiclone is safe for you or if alternative treatments are more appropriate. Withholding this information increases the risk of harmful drug interactions and reduces the effectiveness of your treatment plan.

Final Thoughts

Mixing Zopiclone with cannabis can be dangerous. Both substances act as depressants on the central nervous system, and together they can cause severe drowsiness, confusion, coordination problems, and even breathing difficulties.

If you are prescribed Zopiclone and also use cannabis, always be open with your doctor. This ensures your treatment plan is safe, effective, and tailored to your needs. Never combine prescription medication with recreational substances without professional medical advice.
